So - during the nightmare of my last advneture into snapping my exhaust studs i purchased a spare engine as at one point i never thought i would get the current one back into order....i did....but this thread is now about the spare...
I purchased it with 12,000 miles and 1 snapped engine stud already.....plan was to get the studs removed professionally and replace with stainless steel etc...
Well i managed to get 5 studs out with a campingaz torch, leaves 3 that need drilling out, 2 have snapped flush, one has snapped arkward but that was already done...
Point of the thread is just to document what it turns out like and show some pics of the engine for bits people may not have seen :)
Also any advice and comments good or bad, welcome....
Here it is - little dirty...

Made sure to make notes of current timing chain alignement - did not do that on my current engine!
Note the back marks - and also Cylinder 1 is at TDC on the Compression stroke - cams face outwards as opposed to inwards

Head off...

When i tapped away the Cylinder Head, i distubed the Cylinder, oil leaked out....as can be seen here!
(http://i783.photobucket.com/albums/yy120/antz15/IMG_0283_zpsqgdkspio.jpg)
So decided to remove the oil delivery pipe and coolant hoses and to remove the cylinders as well.....

Off to the engine shop tommorow to leave the head there, once the 3 studs are removed i shall be fitting a stainless steel set :)

QUESTIONS
Why so much deposits on the pistons.....????
19/05/2015
Head at engine shop - 2 studs snapped flush, and one was already hacked off, 4th one although removed, might be some issue with the thread so most likely 3-4 repairs - should be within a week...
Looking at these for replacment studs: http://www.ebay.co.uk/itm/Stainless-Exhaust-Stud-Set-for-Yamaha-FZS600-Fazer-1998-2003-/331542724598?pt=LH_DefaultDomain_3&hash=item4d317c7ff6 (http://www.ebay.co.uk/itm/Stainless-Exhaust-Stud-Set-for-Yamaha-FZS600-Fazer-1998-2003-/331542724598?pt=LH_DefaultDomain_3&hash=item4d317c7ff6)
Unless i can find a Dome Nut variant - will just put my own dome nuts over the top of these...
20/05/2015
So got some deposits off the pistons....stubborn stuff left, used a bit of brake part cleaner i had left and a cloth...

24/05/2015
Starting to clean things a little more now with some natural degreaser, safe around rubbers etc and plastics not too abrasive
Cooling pipes came off ok, no issues there, there is some rust on the end of the pipe i may try to remove...
(http://i783.photobucket.com/albums/yy120/antz15/25B9C3B8-F617-43DB-AB55-B885F8EFABEF_zpsvfis7u6w.jpg)

Also noted these spark plugs, double electrode type as opposed to what i am used to seeing based on my current installed engine...
(http://i783.photobucket.com/albums/yy120/antz15/930943EC-DA6C-4F43-B1AD-3E1A91848933_zpsi6xw7bqa.jpg)
Is it a good or bad thing to have this type verusus the single electrode????

The bores after alittle wipe down....

Valve compressing kit arrived - looks ok and feels strong enough....shall post some pics when i mess around with the spare head i have...

Wow, you've been a busy bee anutz :)
There's some mechanics not done as much in 3 years as you've done in 3 weeks, well done fella, keep up the good work :thumbup
-
....and to think it all started with wanting to get some rust off my downpipes a few months ago.....now i am dismantling a spare engine :lol

:lol yeah, "I'll just do this" syndrome :lol
-
Sorry Anutz, you did ask about the deposits, find it hard to believe that engine has only done 12000 miles. It's the oiliness, unless someone has put oil down the plug holes, but it's not even clean oil.
-
Why so much deposits on the pistons.....????
Most likely the engine was from a bike not used much and spent the last 6 months or year of its life only bing started every couple of weeks for a couple of minutes and never run up to proper temperature or under any load.
-

not going to disagree, don't have the experience to comment on how it should look...but hopefully will get it all running nicely, it is however a little mucky!!!
Just thinking about the "oiliness" - there was LOTS of oil in the head bolt holes and so when i lifted the head off lots of oil ran every where.....anyway...lets see what happens
Also its dirty oil....as well....
-
I was assuming the oil was due to the dismantling process.
-
Have a close look at the pistons and rings.
If there are signs of blow-by down the sides of one of them it might explain the state of all of the piston tops… excessive leakage pressurises the crankcases and more oil mist blows out of the breather into the air box.

thanks will take a closer look and get some pics of the insides of the cylinders - i am not sure if there is a mark on one of them!

It's probably not worth checking ring gaps and if the oil was spilt removing the head shouldn't be too much to worry about. If it was mine while apart i would be tempted to lightly go over the bores with scotchbrite, would be like a light hone. And replace the valve stem oil seals, pattern probably ok. There was an issue with some Yamahas that came with fully synthetic oil and it didn't do much good for running in purposes with the lead on effect of oil burning. I was lucky with my thou as from using a pint every 1000 miles it now uses nearly nothing, i suspected the previous owner used fully synthetic so just changing to semi seemed to sort it.
-
OK so posted a pic on the intial post of the state they pistons are in after a little clean.....better....
In the past i have caused issues when cleaning things TOO much, my brake caliper pistons being one example, took some of their chrome finish..
might less be more here - the main rubbish is off, could what is left affect the engine?
Also a strange query when storing this as it is now in the garage, i am going to stick some cling file over the cylinders and onto the block, any other suggestions or anyone else who has an open engine lying around :lol
-
regards the oil seals, i have an old nackered cylinder head so its something i can look at messing with on that first i.e. how to take the valves apart.....so will look into that and the tools needed...
-
The brake pistons are a different matter and simpler to re-do, for a start its metal to rubber. The skill needed to do the valve seals is less than you have already been doing, when i used to work on engines the only thing that held me back doing valves was finding a suitable spring compresser, the main thing is don't mix the valves up.
-
ok cool :)
So found this....i COULD try make one but from experience if i need the tools now and they are not an arm and a leg i buy them...

Similar looking on one fleabay
http://www.ebay.co.uk/itm/like/231406828878?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&rlsatarget=&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108 (http://www.ebay.co.uk/itm/like/231406828878?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&rlsatarget=&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108)
-
Don't see why the cheaper would not do the job and you might never use it again. Practice on the other head by all means, also don't mix the collets either and when it's back together a light tap with a plastic faced hammer on the end of the valve tip ensures the collet is properly seated. The piston deposits i would carefully remove without removing any metal and is that carbon on the edge of one of the rings, rings need to not be tight in the groove. Keep everything as clean as possible, i would use clean lint free rag to fill/cover holes and lay something like an old towel over the whole thing, clingfilm sounds a good idea as long as it don't encourage condensation.
-
went for the ebay one - seem identical, even the moudling for the case looks the same, but the top right has 2 more valve sizes.....so will see what i end up with!
Will throw some old towels over the components for now, i think when i had my other head off and the engine was in the frame there was some condensate....so towels it is...
Have lots of these for storing stuff : http://www.ebay.co.uk/itm/32-x-100ml-Mini-Storage-Boxes-Plastic-Container-Kitchen-Small-Food-/191481992811?pt=LH_DefaultDomain_3&hash=item2c9537566b (http://www.ebay.co.uk/itm/32-x-100ml-Mini-Storage-Boxes-Plastic-Container-Kitchen-Small-Food-/191481992811?pt=LH_DefaultDomain_3&hash=item2c9537566b)
-
So moving it on a tab, mostly cleaning still, will get the cylinder head back soon and then its gasket time..
But see my last few pics, is the spark any reason it would cause the build up of deposits....
-
Would use a standard spark plug. Remove all carbon with a plastic scraper, you don't want scratches on piston crown or combustion chamber. Don't like the look of that bore, is making me wonder about the rings now.
-
for my benefit....
bore = inside of cylinder, what can you see that alarms you?
i will get some pics of the rings....
this engine is not needed for anyhting right now and won't be really until i decide to swap it in..
so plenty of time to do what needs to be done
-
So after a few PM's and maxzer1500's comments about scotchbrite on the bores, i am looking into it.....any recommendaitons on what type of grade to use?
Also i am thinking can i use the scotchbrite for preparation of the Head and Cylinder gasket sufraces, i use Wet and Dry on my last one after i used a sharp razor to remove old gasket material..
If i can clean up all the important mating surfaces carefully and then scotchbrite as well as on the bores it would be good...
-
I would use scotchbrite on the cylinder bores but you don't want to leave even tiny scratches on the head. The marks on the bore don't want to feel too uneven. Pics of the rings prob wouldn't mean a lot, you really need someone who knows what they are doing to have a look at the parts.
-
OK so i am gonna scotchbrite the bores, the head i will just prep as i did the last one.....scraper and some very fine wet and dry...
regards getting parts looked at - i will post some pics but no plans to take it any where, it came as a working engine so i should be able to re-assmble and then deal with any issues.....
:)
-
Have you got a picture of cleaned cylinder bores? They looked OK to me but hard to tell since still had oil/muck on them
-
Added a pic or two - still need to get the highest ring of dirt off them but they look ok - but thats to me :lol
-
Yeah look pretty good to me too. The ring marks just look nothing more than marks were it's been sitting for a while and nothing to worry about. I think you risk doing more harm than good if you try doing anything more to them
-
yes i think less is more in some cases, especially with this stuff......i need to make sure i am careful when i remove all the old gaskets on the mating surfaces as well.....
-
Look good to me.... ;).....did you see the engine running before you bought it ?
-
no... :o
but i have assurances in email before i bought it ran etc....so any major issues i should be ok....i hope! :rolleyes
what can go wrong eh!!!!! :lol
-
In the intersts of keeping the landing page from killing internet connections with hundreds of image downloads i will just post updates inline...
So cylinder head been drilled and all exhaust stud holes look good, got a stainless steel set on the way i got for 7£ so will fit them when they arrive...

Ignore the head in the background, one i got off ebay and when it arrived the camshaft caps were snapped so its for the bin....
Head and Cylinder gaskets on the way as well...
-
Anyone tell me what this component is - its the white thing i removed from the recess above, i think it must be oil pressure sensor or something....has a orange rubber O-ring, i cannot see it in the service manual - but am still looking
The left hand hole is where the water pump fits, i have removed that for cleaning....to the top right would be the sprocket....hope that gives you a location
Currently cleaning the engine as you can see
(http://i783.photobucket.com/albums/yy120/antz15/A69ECE47-9D7F-4B0C-934A-C13130962CB3_zpsjwyoe3hr.jpg)
-
It looks like the neutral gear sensor. the orange rubber is an oil seal.
When the gearbox is in neutral then there is a brass pin (this pin rotates when you change gear) under were you removed the white plastic unit which makes contact and is a short to ground i think and the green neutral light on the instrumentation lights.
-
thanks for that mobile mouse - indeed that is what it is......
-
anyone ever used shot blast on the engine to clean it up....been reading about soda blast as well which leaves a protectvie film on until you paint it...
or am i asking for a world of pain
-
Not that I've used shot blast anutz, but I've only seen it done on biggish bits of metal etc, not seen it done on engines.
But I've heard/read somewhere about dipping the engine in some sort of solvent, but check up first as I'm not 100% sure what solvent etc
-
google vapour blast... and select images
I have never seen parts so clean, they can do whole engines.
There may be someone who does it near you..
-
will have a look into that, right now i need to take the head down the engine shop, looking at it there are one or 2 tiny marks on it, want to see what they think, one is near a water jacket channel ( assuming thats what its called ) but its not borken the perimieter of it
-

Pistons cleaned up and almost ready to re-assemble, any one recommend a good piston ring compressor they have used?
(http://i783.photobucket.com/albums/yy120/antz15/670A0A74-E42E-4D43-9027-978C7A1FF57D_zpsy4jx0bqg.jpg)

-
What did you use to clean the carbon off the pistons?
-
this stuff....

worked surprisingly well considering its not corrosive or that harsh, green friendly as well...
-
Ok thanks. Is it just a standard degreaser?
-
i think so - not sure what other considerations they are about it - i chose it as it was "green" and was sick of using what i would deems as hasrsh cleaners that made your hands sting if you got a tear in a glove etc, this is a little potent but less trouble, also supposed to be eco friendly.....
